T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of embedded links, many pointing to Shopify domains, which is indicative of a link farm. One prominent URL, https://ttraff.ru/wix?keyword=temario+de+calculo+vectorial, is flagged as a malicious redirector. The document body, though heavily obfuscated, contains this same URL, suggesting the primary intent is to redirect users to potentially harmful content through a deceptive link farm strategy.
Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
